EN S355 plates API standard 650 carbon and low-alloy steel tanks
Upon completion of API standard 650 carbon and low-alloy steel tanks construction, provide Purchase with a Vendor's Certification that the tank conforms to the requirements of API 650 and to the additional requirements as specified.
Inspection of Welded storage tanks Surfaces Exposed during FabricationThe edges of API standard 650 carbon and low-alloy steel tanks plates, openings and fittings exposed during fabrication shall be inspected carefully to make sure that any defects have been uncovered, as well as to determine that the work has been performed properly.Minor defects found may be repaired only after the inspector approves the method and extent of repairs. Materials that have more than minor defects that cannot be satisfactorily repaired shall be rejected.Spot radiographic or ultrasonic examination shall be not less than 6 in. extending along the weld. Spot radiography shall comply with the standards given in 7.15.1.3. Where spot radiographic or ultrasonic examination is applied at joint intersections, the surface shall be prepared and examined for a distance of 3 in. on each side of the intersection, making the minimum length of examination 6 in. on the horizontal weld and 3 in. on the vertical weld.
The foundation design of the API standard 650 carbon and low-alloy steel tanks should meet the requirements of foundation stability and deformation, that is, the API standard 650 carbon and low-alloy steel tanks foundation should not be crushed and the uneven settlement value of the foundation should be within the allowable range. The uneven settlement of the storage tank foundation should be specified in the design process of the safe allowable range, because excessive uneven settlement will reduce the safety of the API standard 650 carbon and low-alloy steel tanks and cause distortion and deformation of the tank wall and bottom plate.
Enterprise vision: to become a world-class innovation base and supplier of steel materials.Enterprise spirit: innovation, truth-seeking, integrity and efficiency.Core values of the enterprise: people-oriented, morality based, value creation, win-win sharing.Employee belief: have faith, can contribute; have dream, can fight; have action, can create; have value, can be happy.Employee belief: have faith, can contribute; have dream, can fight; have action, can create; have value, can be happy.
Management information and high efficiency. Because of the rapid flow of API standard 650 carbon and low-alloy steel tanks goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation
The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the API standard 650 carbon and low-alloy steel tanks principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
